我已经在带有 xfce 的 Ubuntu 16.04 LTS 服务器版本中安装了 xrdp，但我无法使用默认 RDP 通过 Windows 计算机登录。它显示为已连接/已加载，对话框关闭，RDP 自动停止。
以下是可能有帮助的 sesman 日志数据。

我不确定问题出在哪里。任何帮助都值得感激，我是 linux/CLI 领域的新手。如果有帮助，此服务器从 12.04 LTS 升级到 14.04 和 16.04 LTS。
答案1
我看到有人报告发生这种情况是因为用户会话在 X 窗口中打开并建议在使用 xrdp 之前注销。
答案2
我也为这个问题苦恼了好几天。我通过添加以下两行解决了这个问题xrdp.ini：
autorun=Xorg
max_bpp=16
并在 RDP 会话中选择xorg；xvnc连接工作正常。
